Relax your arm, imagine it gently flowing downwards, like a feather or a bubble.
When you mangage to relax it, the vibrations will likely be gone.

September 2, 2020, 5:13 AM · If you're talking about the bow vibrating in the middle of the bow stroke you need to be sure you've got a proper grip on the bow and maintain constant slight pressure with your index finger to counter the tendency of the bow to bounce as it travels across the string. Keep your arm relaxed and in proper posture but I have found that when my bow bounces I'm not maintaining proper pressure on the string. Not heavy pressure, just consistent pressure.

Vibrating would be quite interesting indeed.

September 2, 2020, 8:51 PM · You might be interested in Nathan Cole's youtube video, "Safety move eliminates violin bow shakes." As he says, the bow is made to bounce. I have the most trouble on down bows in the lower half of the bow. What helps me the most is to make sure my bow is tracking parallel to the bridge. And, some bows seem to shake more than others. But apparently all do to some degree.

It's good to see some serious math being put to work in explaining a phenomenon we've all experienced some time or other. It's what one would expect - the vibrations of a string interacting with the natural vibrations of a moving bow that is causing the string to vibrate.
September 3, 2020, 9:03 PM · If it's a bow phenomenon rather than muscular, it's related to camber and a REALLY GOOD bow maker can remove the vibration. I've seen this done many times, with spectacular success by people who know exactly how it's done.

But the regular folks here are ok!
Edited: September 4, 2020, 4:50 AM · Sometimes it is annoying when the OP doesn't make any further comment (especially if the question is contentious), but my finding is that quite often if I interfere with answers to a question I ask, all I do is muddy the waters, so it's sometimes better to see how the conversation goes under its own steam, rather than try to direct it. e.g. I might try to refine a definition only to find people think I'm redefining the entire question (indeed I am, if they misunderstood in the first place, but by then the whole thing is usually shot to hell anyway).
Also, if the OP is young, they may be confused or embarrassed, and it's better not to press them.
September 4, 2020, 7:18 AM · As Michael said, there is the possibility of an issue with the camber. A bow can tremble in certain sections when there is a flat spot in the curve. Take it to a bow maker to have a look if the problem still persists.
